Newtec is providing Gateway Communications, a provider of carrier and business network solutions in Africa, with an end-to-end IP trunking solution to increase the bandwidth efficiency of its intercontinental data links between Europe and Africa.

Previously, Gateway’s satellite links performed as independent SCPC point-to-point links using Turbo coding modulation products. By replacing these products with Newtec’s Elevation DVB-S2 system, Gateway has managed to achieve a 50 percent increase in satellite bandwidth efficiency. This success was made possible by combining several IP trunking signals for IP and GPRS services into one satellite carrier, allowing saturation of the transponder for maximum efficiency.

Newtec’s Elevation devices are native IP products that seamlessly integrate with terrestrial IP networks. They feature standard Ethernet/Gigabit Ethernet interfaces and embedded IP routing and processing functions.  The unique Cross-Layer optimization functionality boosts the efficiency and performance of the network by using the high level of integration of the Elevation devices to optimize the transmission at all layers of the OSI model and exploit all possible inter-layer dependencies.  The product line offers an exhaustive implementation of the DVB-S2 standard, including features such as Multistream, Variable Coding and Modulation (VCM), Adaptive Coding and Modulation (ACM), Generic Stream Encapsulation (XPE/GSE), and the higher modulation schemes 16APSK and 32APSK. With FlexACM, a unique combination of DVB-S2 ACM capabilities with traffic shaping and encapsulation, the Elevation product range can double the available throughput, and guarantee 100 percent availability of the link reception.


Newtec is one of the market leaders in satellite communications, offering highly reliable products and solutions including DVB modulators, Digital TV & Radio Distribution networks, interactive TV networks, IP Broadband Access Networks as well as products for optimisation of Internet traffic to customers worldwide.  With its ambitious policy of re-investment in R&D, Newtec is recognized as a forerunner in several innovative satellite communication technologies, which have been published as industry standards (DVB, DVB-S2, DVB RCS and iSatTV Cenelec pr EN50478).  Established in 1985, and headquartered in Belgium, the company has regional offices located in Stamford (US), Singapore (Singapore), Beijing (China), Dubai (UAE) and São Paulo (Brazil). Newtec’s Tellitec IP Software products are engineered in Newtec’s research and development facilities in Berlin (Germany). In Brest (France), Newtec's subsidiary TurboConcept develops  Intellectual Property Cores for turbo and LDPC building blocks.
